Abstract
Feedback from the front facet of an integrated DFB laser with an elect roabsorption modulator generates additional chirp to the single modula tor. The reduction of the sensitivity to that feedback is in tradeoff relation with the external differential quantum efficiency and the sin gle-mode yield. We introduce a figure-of-merit for the feedback sensit ivity. It is obtained from the modeling of the small signal frequency modulation (FM). It indicates design rules for low-chirp and high-effi ciency devices.
